This tweak will make you searching contacts very easily by T9 logical.
1. As shown below, you can simply enter "27753" or "apple" to get all apple's contacts.
2. Of course, you can also enter sub-string of number, like "7272" to get Apple.HK.
3. For Mandarin user, you can use full Chinese phonetic alphabet, or First Phonetic Letters to do the searching. e.g. "zhangsan" (94264726) or "ZS" (97) for the contact named "张三".
If you are interested in this tweak, you can add my experimental cydia repo, https://TweakiOS.com/ and install EasyDialer.
